We need re_query to cache and return Chunks directly.

That also means updating all the views and all the many many query layers to make efficient use of these new APIs.

There are some secondary requirements we really want fix:

• LatestAt & Range results should be one and the same, and still somehow do the right thing automagically.
• These APIs should work nicely with the idea of defaults/overrides and such.
• We still need a gazillon helpers for doing thing like "get me the deserialized latest mono instance of this component at this path".
